Abstract
Inactivation of the MXAN_0853 gene blocked the production in Myxococcus xanthus of straight-chain fatty acids which otherwise represent 30% of total fatty acids. Despite this drastic change in the fatty acid profile, no change in phenotype could be observed, which contrasts with previous interpretations of the role of straight-chain fatty acids in the organism's development.
摘要
MXAN_0853基因的失活阻止了黄色粘球菌中直链脂肪酸的产生，否则直链脂肪酸占总脂肪酸的30%。尽管脂肪酸谱发生了如此剧烈的变化，但未观察到表型变化，这与之前对直链脂肪酸在该生物体发育中作用的解释形成了对比。
